[PATCH] mmc: fsl_esdhc: Fix enablement of UHS mode

[Fabio Estevam]

From: Fabio Estevam <feste...@denx.de>

Since commit 1a7904fdfa7d ("mmc: fsl_esdhc_imx: Use esdhc_soc_data flags
to set host caps") the following SD card error is observed on an imx7d-sdb
board:

U-Boot 2023.04-00652-g487e42f7bc5e (Apr 05 2023 - 22:14:21 -0300)

CPU:   Freescale i.MX7D rev1.0 1000 MHz (running at 792 MHz)
CPU:   Commercial temperature grade (0C to 95C) at 35C
Reset cause: POR
Model: Freescale i.MX7 SabreSD Board
Board: i.MX7D SABRESD in non-secure mode
DRAM:  1 GiB
Core:  100 devices, 19 uclasses, devicetree: separate
PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x10
MMC:   FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2
Loading Environment from MMC... Card did not respond to voltage select! : -110
*** Warning - No block device, using default environment

Fix the problem by only asserting the UHS_CAPS when supports_uhs() is true
instead of doing it unconditionally, only based on the defconfig option.
